(A little less snippy response would have been appreciated.)I fully understand the mechanization and process of Rifle usage.
What I mean is this: is the only way after takeoff to fly around looking for something the TGP can hardlock to slave the mavericks to?
You cant really do it on the ground WOW AFAIK because the missile step wont work on the ground, correct?
What is the most ideal way?
Surely in real life Viper pilots aren’t flying around after takeoff looking for something to TGP-lock on?
Thanks and regards.

Try to set your ground jettison switch to enabled

no, Mower is right, the Boresight on the ground does not work in BMS
I tried when designing the new simplier Maverick missionThe idea was to use these big fat B-1s to boresight on the ground. But no way it can be done.
Not for the reason Mower says though but rather the wonky behaviour of the cursor when not pointing down.
So yes in BMS, you need to do that in the air
-
I’m not sure if they do that, but the best results for boresighting would be in the air. Since the wing flexes differently on the ground and airborne, a ground boresight would be slightly off once airborne.
(We dont model that in BMS).
-
So here’s the challenge I run into and my workaround:
In RL Im sure we have alot more terrain objects that a TGP could lock onto but in the BMS terrain we have very little, mainly buildings here and there.
So, what I do is set up a waypoint after takeoff that takes me inbound to a major city so I can find something for the TGP to lock onto. This of course works but it burns gas and is not very realistic.
So I was wondering if that remains the best way to boresight my Rifles, sounds like it is.

Piece of cake, just plan ahead and place a steerpoint at a bridge or something along your route
-
You can boresight in VIS mode as well. Fairly easy to visually find a city, put the TD Box near it, adjust with TGP, then boresight.

And if there is overcast? You see the problem, your workaround is valid but not perfect, though nothing is.
BTW you’re not really that guy in your avatar from the AotK video are you?

how about boresighting on another aircraft?

(We dont model that in BMS).
Because of parallax error between the HUD and missile seeker longitudinal axis, a ground boresight should be accomplished on an object that is at least 3000’ away and an airborne boresight on a target that is at least 3 miles away.

Use the MFD OSB’s to select the station. No need to use the MSL STEP.
In RL , pilots boresight on ground or in the air. Air boresight gives the best result…
They don’t fly around looking for something. They already know where they will boresight before they get in the jet. -
how about boresighting on another aircraft?
Well maybe but it’s not reliable to be an option all the time shortly after take off…unless I can persuade my AI wingmen to fly out in front of me…2 take the lead while I boresight Rifles on you…

My problem is This ,
When in the air wpms on, sms page set to maves Timed out, Tgp up and tgt locked I try to use the missile step switch will not go to the mav page So I can uncage the weapon .
Change the mfd to any other page and the missile step works fineI also printed out the procedure from the manual and followed it step by step. still will not missile step
Checked my setup in the controllers page all callbacks work fine Keyboard and Hotas settings
Crazy -
to my understanding this is an ancien regime, meaning it is historical but no longer in usage. The aircraft when fitted with the agm65 series capable of slaving to the TGP is simply an OSB button press and then a veto or no veto confirm on the WPN page, which is also in the SMS page. The cursor enable switch also acts as the bore/slave when this is enabled, allowing the seeker to be broken off the merged cursor of the TD box, both in the hud and in the SOI. Put plainly, this process is not in any real jet currently operating in the foreign or domestic fleet, and the functionality that led to this modeling has been streamlined.

Prepare AGM-65
- Press DMS right until SMS format is visible.
- Press SMS OSB 7 “PWR ON” to power AGM-65.
- Press DMS right until WPN format is visible.
- Set master arm switch to SIMULATE.
TGP Acquire
Approach- Set autopilot roll switch to STRG SEL. (optional)
- Set autopilot pitch switch to ALT HOLD. (optional)
- Unfreeze simulation.
- Fly toward boresight target at 300-450 KCAS and 6,000’ until “F005.0” range on HUD.
- Freeze simulation.
- Wait for NOT TIMED OUT to disappear from WPN format.
Point Track With TGP
- Press DMS left until TGP format is visible.
- Observe ship on TGP format.
- Press TMS right to command TGP to AREA track. (optional)
- Slew TGP crosshairs directly over ship.
- Press TMS up to command TGP to POINT track.
Track With AGM-65
- Is handoff is successful within 3 seconds?
Yes: Skip to next section.
No: Press DMS down to set WPN format SOI. - Press pinky switch to select wide FOV on WPN format, if necessary.
- Slew WPN crosshairs over ship.
- Press TMS forward to command missile track.
Record Boresight
Stations 4&6, AGM-65G- Verify TGP and WPN tracking same object.
- Press WPN OSB 20 “BSGT” to save boresight data.
- Press MSL Step button to select station 6.
- Press pinky switch to select wide FOV on WPN format, if necessary.
- Slew WPN crosshairs over ship.
- Press TMS forward to command missile track.
- Verify TGP and WPN tracking same object.

- Press uncage switch to produce AGM-65D video.
- Press pinky switch to select wide FOV on WPN format, if necessary.
- Slew WPN crosshairs over ship.
- Press TMS forward to command missile track.
- Verify TGP and WPN tracking same object.
- Press WPN OSB 20 to save boresight data.
Station 7 - Press MSL Step button to select station 7.
- Press uncage switch to produce AGM-65D video.
- Press pinky switch to select wide FOV on WPN format, if necessary.
- Slew WPN crosshairs over ship.
- Press TMS forward to command missile track.
- Verify TGP and WPN tracking same object.
- Press WPN OSB 20 to save boresight data.
Secure
Secure AGM-65- Set Master Arm switch to OFF.
- Press DMS right until SMS format is visible.
- Press SMS OSB 7 PWR OFF to power off AGM-65.
- Press SMS OSB 6 to select desired weapon.
- Press MSL Step switch to select desired station.
Secure Sensors
- Press TGP OSB 9 “CZ” to zero system deltas.
- Press TGP OSB 1 then OSB 10 to select STBY mode.
- Press DMS left until FCR format is visible.
- Press FCR OSB 1 then OSB 6 to select GM mode.
Return to NAV Master Mode
- Press ICP AG to select NAV master mode.
Notes
- Practice until freezing simulation is not required to boresight two stations of a single type of AGM-65 on one pass.
- Do not allow PWR ON time to exceed 30 minutes including simulation freeze time.
- If failed handoff produces avionics fault in PFL, press F-ACK button and continue calibration. Fault will clear on next successful handoff.
- TGP & AGM-65 tracking may be accomplished in any order. Boresight data is successful when TGP and missile are tracking same object when BSGT OSB is pressed.
- Some AGM-65 variants have protective covers requiring the uncage switch to remove before video is produced.

Why dont you explain for us the whole MBC design process? Im sure such a post would be well received.

I had some “Aligning” on the ground in 4.33 but I had to put a ground vehicle some where in an appropriate place.
Feel your pain, In flight with 2 or 5 others, “I’m aligning the Mavs, ill be quick” Roger they say and fly of and do the mish with out me, By the time I get there its Bingo time.

It shouldn’t take too long really. Just have a flight plan leg fly over a briefed landmark, like a building, VOR, ship etc. In the same or following leg, you can then do your TFR safety/SWIM checks. Then you’re all tested and checked ready for PP, Fence in, and the boomy stuff.

well generally speaking, this is a “like model” but not anything close to a procedure, now , or ever, within the real jet. Imagine pilots nose wheeling around looking for something to dope their sights on. No I imagine this is only in the game because someone with aviation experience knows about the old boresight dope sights used for aligning guns at the end of some range runways, at least that’s my logical assumption, and you got a like process.
initially there was very little functionality shared between the hotas and the maverick, these control schemes and needs were first expressed during the ground trials of the warthog. originally there was a comply lever which changed the SOI of the slew hat. you can see this actual fusing and mechanization was rather common, not to get all diagram about it, but before it was changed to be purely electric and automated, the fuze, and the trigger had to communicate, and a man had to be in the loop. ( thus the holding down)- therein you’ll see in very old and out of use documentation, the term " half action" we’re literally talking about extra buttons.
It’s convoluted, there are different airframe reasons, mainly to do with native avionics, depending on what and where but by the time the D is standard issue, to be more specific, by the time USMC hornets and spanish hornets could triple rack mavs on the outboard wings, and the land hornets had their nose wheels redone for longevity in land life the agm65 family had been redesigned to work plug and play with the lightening and the sniper. this was mainly done to harmonize UFC functionality and brevity when the goal was to start using the E model mainly, which is laser guided, and requires L targeting from a pod, a jtac, or a buddy.
The ease of employment being the goal. If you want to really crank on the details of maverick testing the trials over germany from 1979-1981 have recently received renewed public interest because of the testing and shelving of hypervelocity air to ground pods which were also on the test schedule. My point being, there are volumes of documents on each aircraft during the trials, from the camo and countermeasures they used, to the flight times and weapon loadouts. Mavericks under performed in trials against moving targets and were not considered intuitive.
I think to get defensive about a convoluted process that isn’t in any real jet is counter productive to a simulation.
